John Deere 1640 Hi/Lo Part 1 Stripping and Inspecting

[Music] well on the bench here you can see all me bits and pieces and as you know I never pulled this tractor apart so we can't actually risk not looking at anything so all these high-low parts a lot of them here all the plates were pulled out and things like that so we'll put them aside for the moment we won't assemble them just to pull them apart again one of the main problems with these tractors is on the high-low break here now on the high-low break getting it engages and locks up a couple of plates to to grab a housing that through these slots up here you can't really see but anyway through these slots up here and that either holds or or lets a piece of the planet return depending on whether you want a low or high range so so on tractors if you have attracted that when you put it in high on rabbit turtle you put it in high let it I they'll hop off the track to go and open the gate you hop back in all of a sudden you've got no steering no hitch something like that yeah you've run out of hydraulics because of the leak within the high/low here so you'll find also that sometimes if you drop it back into low the problem goes away and in high this is your high brake this piston is engaged so what we'll do is work through now you probably don't need snap ring pliers for this but we'll use them anyway there's a snap ring here and the sole purpose of that snap ring is to not let this piston travel too far it holds it in place so if something else bug is up here it all stays there so we take that off and then this piston just comes out now look at this bingo now that ring when I find the later tyke one here here we go okay a problem with these tractors is this o-ring here and it's an l6 double two seven to the l6 double two seven to seal it gets a bit of heat on it and it gets a gap in it now just a little gap in it the oil disappears out through the system here now they were a little troublesome anyway because when you have a when you have a piston ring sitting like that sitting together there's always a gap and the system was never designed all that well and John Deere in their wisdom they thought well if we take a steel piston out piston ring out and we put a neoprene one in well this one here has no gap it's a better sealing surface and look it is but the problem is when you're doing hard hydraulic work with the tractor and there's another problem somewhere the or gets really hot and when the oil gets really hot sometimes these get overcooked and they go a brownie color and they just crumble they fall apart so for this to have that piston ring in it guess what Lance is using this I know the mod from John Deere was to go the other way but I can put this packing in I can know that we're never gonna lose high low like it's a I think it's a good thing that's why I said bingo I thought oh what a beauty my tractors never work hard anyway they just poke around ear slashing and Machinarium but I do sell some one if I sell one from time to time I don't sell them on this I know they're perfect so also we have a hook ring here and a under your upgraded the hook ring to this so another neoprene one so they can go back under the bench in the John Deere parts section and look I'm I'm really pleased with that I tell you but look what we have to do and it's the same as with any other clutch pack we have to make sure that these steel plates are not war or that the steel piston rings are not warm beyond using them so if we get that over the center of the screen a little bit so we hook that together pop him in here now we we try and get this as level as we can and we do that so that we know it's all good okay now can you see see down there where the two hooks are there's two or three fare at each end of the hook but there's a nice big Center there I think you can see it just there so that big dot in the middle that means we've got plenty of room there so that's good we're going to use that now the piston ring here some people might disagree with me with putting this back in but oh that's good I just um I just think it's the way to go in my instance now if we just poke this in will shut down somewhere near where it would run pull that out and you'll see a piston ring gap there if I get the buddy light right there we go you'll see that little gap there so when we first put the tractor back together that will always have that tiny little leak there they brought them out for years with that when you want to reimplementation a hydraulic motor that's probably worth looking at but you can't always lock back in too low to get you full supply but this here I can put this tractor back together now I believe that that's nowhere at all it's done 3,000 ailes 3070 I think and initially when I put it back together the other oring would have given me a better seal but for a shorter time me now been putting this tractor back and knowing that this is in good order and I have the steel rings that's fine now I don't believe I may be wrong but in Australia I don't believe we can buy these rings anymore two steel ones I think they automatically go across to the neoprene this year I've give it a bath you have the four pipes here I can't remember exactly which way which is which but it's something like four-wheel-drive high-low Lube pdop do brake and high low or something like that so yeah I can't quite remember that I would have to look it up this one he is obviously high like there's a line straight up that's the high low and this one must be lube perhaps neither here nor there I just can't remember it and I haven't looked it up in the book to tell you it's not all that important now each of these pipes comes in and have a look on them and see if you can see right through them like you can on this there is a rings in here that can be replaced and mine are nice and soft so whether I do or not I probably will sins on here now on your PDR on P do break look have a look at all of them no way that was leaking and there was a pipe like this with a restriction in it and that was to engage your PDA slightly slower you know on a big implement you just don't want to go burn in it that brought your PDA packin gently but look all these are really good that dumb no rings here enough that's beautiful now the 50 series housing where these pipes go in the 50 series housing has a little dimple there and I usually there is a room for the eye rings I see put the eye rings in but that little dimple it's for a plastic seal that goes down over the top and it it gives extra sealing to here so anyway like I'm I'm tickled pink lucky dog wagging his tail having this proper ring in there so this will go in like that try and get that as central as we can once again a bit of your favorite grease around it there's also a bush here that supports your highli have a look that's no not cookin this is this is good in this instance I think we're getting a bit lucky with this tractor might be the famous last words yet but we'll see just make sure that's good all the way around yeah look just in there I can actually see the original machining marks the dark cast bloody beautiful ok we'll pop a bit of grease around here just to help getting it in bring this down and just wobbly Maria with your fingers a little bit no pressure now with the ones with the neoprene seals you do have to get in there with an o-ring pick and fold at all in it that is a little bit more difficult than this job yeah the inside one just sits on and the one on the piston here you bring it down and you actually have to just feed it in through the holes here just a little bit so look that's great I'm really pleased with this I'll put this snap ring back on I can't go anywhere but they leave on the grease so it accurate full of dust and whatever else can be floating around on TV shitty well we do have plates and things to go in here and I suppose we can go there but we can't compress it now the reason we can't compress of this stage is drop that in there and then a steel one goes you have a picker one not not the thickest the right into one then a steel plate now these still there's no it doesn't look like the lining wants to come off but what I'm trying to explain to you with this there's with this other clutch pack you have the sealing rings here and this is where that Bush goes well you can't actually set all this up and hope to just slide that in this has to line up with the clutch plates so you leave it loose slide the center and give it a wriggle around make sure the clutch plates are aligned then you pull it out and put your tension on the Belleville spring to hold it all together so for the moment I'm not going to muck with that we'll put that aside this is your high-low clutch the the other day when we're doing the video on the making the tool I pulled this apart with your Springs now your Springs they go together on the outside there and then they go back to back there so that gives you a little spring pack and that's what you can press so once we've got that off this video wise you just have a piece of wood well give the camera a kick Green she's good there needs a bit of wooden you're just a [Music] [Applause] little bit along and there's the piston ring for the high/low yeah we'll have a good look at that they looks good now we'll clean the housing yeah slide this in once it's label once you believe it's true all the way around have a look for your ring gap that there's about ten there that'll be fine very high low it's probably a tad aware on that but not much and also as on the PDA pack we have a three nine three oh four here which is a rubber packing we take that and throw it away regardless it may be in good order but that's okay so that needs taking away I'm washing a little piece there now this is our planetary for our high low and that's all being pulled apart as well so what we have to do now we can pull the center out now the gears run on here these gears here run on there and this piece here that's where the that's where the clutch plates run only has a couple of clutch plates a couple of internal spawn so what we look for here is tooth where if it's been running a bit crooked we look to see if this is rough along here so that when their plates are on they can float freely the housing looks good now at this stage we can pull this gear out and have a look and take note of the thrust washer there they feel really good and look at your Bush this fellow here and look that's okay too you can still see the white on it and a little bit away not much yeah these pins here they come out and we look for where in there now they get where there's a little ball that locates it I'll just put that over there there's a little ball that locates it and stops it from turning and then we have a thrust washer a couple of needle rollers and a thrust washer so that's the that's the setup inside the gear I can probably put it on the shaft so you can see it better looking for where on there galling we're going to clean it up make sure it's nice and clean once again we looked at the Harding's not going here the Harding's not gone here or here that looks good they'd have to be matched or anything like that there it's gonna run away on me I'll put a thrust washer there and the same here and once again because I didn't pull the tractor apart we have to look at everything we don't know if someone's sleeve this out and forgot a bearing or what they've done we just don't know so there's the bearings again check the gear so so that's the high/low stripped down I'll go and wash all these parts up and we'll come and cover assembling it and there's a few little things you need to watch out for so you come back and have a look yes that'll be the end of this video or go and clean up and get ready and the next video will mainly be assembling your hi-low pack and what you need to look out for [Music] you [Music]
